Why is the membrane described as a phospholipid bilayer? It is described as a phospholipid bilayer because there are two layers of phospholipid molecules. 2. How does the arrangement of the phospholipids form a bilayer? The phospholipids arranged in two layers so that the

Introduction The natural source of both plasma and electromagnetic radiation (EMR) is the sun. There are various similarities such as the presence of electric and magnetic field in both EMR and plasma. Both transport contain energy and are ubiquitous in the universe. However‚ there are large differences between EMR and plasma. Differences between EMR and plasma EMR is energy that propagates through a medium in the form of EM waves. It has an electric and magnetic field which oscillate in

2. Experiment 2.1. Cold Plasma Jet System This research used a cold atmospheric pressure plasma jet system with an inclined style of treatment (gradient = 45o) as shown in Figure 1. This system was developed based on Teschke et al.32 Medical-grade argon gas (99.999% purity) produced by the Samator Company (Indonesia) was used as a carrier gas. Two aluminium foil ring electrodes were used around the quartz tube for this system. It had a quartz tube with a 1.5 mm inner diameter and a 2.7 mm outer

Bio152 Final Exam Review Essay Questions: Quest 1-2: Describe the fluid mosaic model of plasma membrane structure and list the major components of the membrane. How did scientists discover that the membrane was “fluid”? Explain one experiment that we discussed. • The fluid mosaic model of plasma membrane was the idea that lipids or proteins could move in the membrane laterally. The plasma membrane is made up of a phospholipid bilayer and controls a lot of what goes in and out of the membrane by the

Case Discussion – Chapter 5 Trade in Information Technology and U.S. Economic Growth 1. During the 1990s and 2000s computer hardware companies in certain develop nations progressively moved the production of hardware components offshore‚ often outsourcing them to producers in developing nations. What does international trade theory suggest about the implications of this trend for economic growth in those developed nations? Answer When production of commodity-like components

Evaluate conferences as a tool of international diplomacy. The role of conferences in international diplomacy have increased over the years‚ by gathering official representatives from various sates in order to engage in multilateral discussion. In order to resolve international conflicts‚ however conferences are not the most effective in doing so. Even though conference participants are for the most part official representatives of their respective governments‚ in some cases they have little or no final

Outline the roles of membrane at the surface of the cell The plasma membrane encloses the cell‚ defines it boundaries and maintains the essential differences between the cytosol and the extra-cellular environment. The separation of the internal and external environment maintains a constant internal environment which is essential for the cell to function efficiently. Membrane receptors can interact with specific molecules corresponding to stimuli such as hormones to generate a signal cascade which
